This is an overview of some of the main family members.
The Willmott Family are connected to the Rich Family via the Marriage of Sarah Ann Willmott and George Rich on 29th June 1875 in Oundle, Northamptonshire.
I have only been able to go back 2 generations to Sarah Ann's Grand-parents; John Willmott born circa 1799 in Cotterstock, Northamptonshire and Elizabeth Stevens born circa 1793 in Barnwell, Northamptonshire. They were married on 22nd October 1822 in Oundle, Northamptonshire and had 7 children: Elizabeth 1823, Samuel 1825, John 1827, Leonard 1829, William 1832, Catherine (or Caroline) 1835 and Francis 1839.
William Willmott married Rebecca Brawn (born 1834 in Winwick, Huntingdon) on 24th December 1854 in Oundle, Northamptonshire and they had 7 children: Sarah Ann 1856, William 1857, Samuel 1861, Mary Elizabeth 1863, Kate 1865, Alice 1868 and Leonard 1874. There is a long gap between Alice and Leonard so there may well be more children for which the records have been lost.
Sarah Ann married George Rich on 29th June 1875 in Oundle. Although I have found the Death registration for George Rich, I have been unable to find any record, either Parish of Civil for the Death of Sarah Ann.
